What is Google Merchant Feed?

Google Merchant Centre is an online account which companies [or individuals] can use to incorporate all the products they already sell online into Google’s feed. When people search for specific keywords, products then surface within the results [with images].

However, not all results contain images of items to buy and when they do, it is very competitive as there are countless retailers trying to maximise their chance of showing up as a result. This is because within the portion of text, images are very obvious and draw attention.
